In late November, more than 110 people gathered at a crowded Christmas party at a restaurant in Oslo, Norway. Most of the guests were fully vaccinated. One had returned from South Africa just a few days earlier and was unknowingly carrying the omicron variant of SARS-CoV-2.
Ultimately, about 70% of the partygoers were infected.
Scientists who traced this superspreader event concluded it was evidence that omicron was "highly transmissible" among fully vaccinated adults.
